Rails 5 DB迁移错误

Question

我正在尝试将我的rails应用程序部署到生产中，但是在尝试调用rake db:migrate时遇到错误rake db:migrate我得到的错误是ActiveRecord::StatementInvalid: Mysql2::Error: Illegal parameter data type bigint for operation 'get_lock': SELECT GET_LOCK(2398406209365187035, 0)我看不到哪个迁移导致了这个，我的迁移都没有：limit设置为从integer转换为bigint

这部署在舞台上很好，所以我不确定问题出在哪里。

我的迁移如下：

class CreateDatabase < ActiveRecord::Migration
  def change
    create_table "vuln_sets", id: :integer, force: :cascade, options: "ENGINE=InnoDB DEFAULT CHARSET=latin1" do |t|
      t.string "vulntype", null: false
      t.string "displayname", null: false
      t.string "bulletinfamily", null: false
      t.integer "vulncount", default: 0, null: false
      t.boolean "active", default: false, null: false
      t.timestamp "timestamp", default: -> { "CURRENT_TIMESTAMP" }, null: false
      t.index ["vulntype"], name: "vulntypeindex", unique: true
    end
  end
end

第二次迁移：

class DeviseCreateUsers < ActiveRecord::Migration[5.0]
  def change
    create_table :users do |t|
      ## Database authenticatable
      t.string :email,              null: false, default: ""
      t.string :encrypted_password, null: false, default: ""

      ## Recoverable
      t.string   :reset_password_token
      t.datetime :reset_password_sent_at

      ## Rememberable
      t.datetime :remember_created_at

      ## Trackable
      t.integer  :sign_in_count, default: 0, null: false
      t.datetime :current_sign_in_at
      t.datetime :last_sign_in_at
      t.string   :current_sign_in_ip
      t.string   :last_sign_in_ip

      ## Confirmable
      # t.string   :confirmation_token
      # t.datetime :confirmed_at
      # t.datetime :confirmation_sent_at
      # t.string   :unconfirmed_email # Only if using reconfirmable

      ## Lockable
      # t.integer  :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts
      # t.string   :unlock_token # Only if unlock strategy is :email or :both
      # t.datetime :locked_at


      t.timestamps null: false
    end

    add_index :users, :email,                unique: true
    add_index :users, :reset_password_token, unique: true
    # add_index :users, :confirmation_token,   unique: true
    # add_index :users, :unlock_token,         unique: true
  end
end

Answer 1

我今天遇到过这个问题。 似乎MySQL / MariaDB的get_lock实现已经改变：

在MariaDB 10.2上：

> select get_lock(1234567890, 0);
+-------------------------+
| get_lock(1234567890, 0) |
+-------------------------+
|                       1 |
+-------------------------+

在MariaDB 10.3上：

> select get_lock(1234567890, 0);
ERROR 4079 (HY000) at line 1: Illegal parameter data type bigint for operation 'get_lock'

将Rails升级到5.1.6。
